Sink and tap installation in Cardiff

Thinking about sink and tap installation in Cardiff?

People in Cardiff with low water pressure sometimes find a new tap disappointing, so checking the pressure before choosing a tap or boiling water tap saves trouble later.

If a new dishwasher or washing machine is going next to the sink in your Cardiff home, the trap and waste connections usually need changing as well. We cover all of Cardiff, including the CF10, CF11, CF14, CF15, CF23 and CF24 postcode districts, and travel out to neighbouring towns across South Glamorgan.

Guide prices for sink and tap installation in Cardiff

Typical sink and tap installation prices for homes in Cardiff, including VAT and adjusted for Wales. Your own figure depends on the size of the kitchen, the layout and what is moving. Costs across Wales tend to sit under UK averages, which these ranges reflect.

What kind of kitchens do we fit in Cardiff?

You will find Victorian terraces, Edwardian villas, post-war estate houses and waterfront apartments throughout South Glamorgan. Cardiff's Victorian terraces often have a long galley in the back addition, while Edwardian villas in Penarth may have a separate kitchen and breakfast room.

Busy on-street parking in terraced areas and apartment blocks with booked lifts can affect delivery times and how long worktops are carried in. Much of South Glamorgan has soft to moderately soft water, though some parts are harder, so check with your supplier before choosing a filter.

Regulations for kitchen work in Cardiff

In Wales, sink plumbing should meet the water fittings regulations, and a new connection to an underground drain involves building control. Electrical rules differ from England: adding a spur or socket for a boiling water tap extends a kitchen circuit, which is notifiable under Part P in Wales, so it is certified through a competent person scheme or building control. Swapping a sink and tap on existing pipework needs no approval.

Listed buildings and conservation areas, including parts of Cardiff and Penarth, may need consent for new vents, and apartment owners usually need the freeholder's consent.

Planning ahead

For a ceramic farmhouse-style sink in your Cardiff kitchen, confirm the base unit is designed for it, as a standard sink unit may not carry the weight.
Choose the sink before stone worktops are templated in your Cardiff kitchen, so the fabricator can cut and polish the undermount opening to suit it.
Ask for the dishwasher and washing machine hoses to be routed so they cannot kink behind the units once the appliances are pushed back into place.
Keep isolation valves reachable under the sink, so the tap can be serviced or a leak stopped without turning off the whole house supply.

Questions about sink and tap installation in Cardiff

How much does sink and tap installation cost in Cardiff?

For plumbing in a new sink and tap, budget around £180 to £370 including VAT in Cardiff. That reflects typical costs in Wales; we confirm the actual figure in writing once we have measured up.

Do you cover all of Cardiff?

Yes. We work across Cardiff, including the CF10, CF11, CF14, CF15, CF23 and CF24 postcode districts, and nearby towns such as Penarth and Caerphilly. Book a free survey visit and we will arrange a time that suits you.

Can a dishwasher and washing machine drain through the sink waste?

Yes, in most kitchens. The sink trap can take an appliance connection on a spigot, or a separate standpipe can be fitted. The appliance hose needs to rise to the height its manufacturer specifies before it drops to the waste, so dirty water cannot siphon back. Two appliances can usually share a double-spigot trap, which we plan with the sink.

What do I need for a boiling water tap?

A boiling water tap needs a tank in the cupboard under the sink, usually a socket or fused spur to power it, and often a filter, particularly where the water is hard. Some models have a minimum water pressure, so check yours before buying. The tap also needs a correctly sized hole in the sink or worktop and enough clear cupboard space for the tank and pipework.

Do I need isolation valves under my kitchen sink?

They are strongly advised, and we fit them as standard. An isolation valve on each supply to the tap, and on each appliance supply, lets you turn off the water to one fitting without shutting off the whole house. That makes changing a tap cartridge or dealing with a leak far simpler. The valves are left where they can still be reached once the cupboard is in use.
